范例

Example #1 Updating a record in the database

<?php

// open in read-write mode
$db = dbase_open('/tmp/test.dbf', 2);

if ($db) {
  // gets the old row
  $row = dbase_get_record_with_names($db, 1);
  
  // remove the 'deleted' entry
  unset($row['deleted']);
  
  // Update the date field with the current timestamp
  $row['date'] = date('Ymd');
  
  // Replace the record
  dbase_replace_record($db, $row, 1);
  dbase_close($db);

// simply use 'dbase_get_record' instead of 'dbase_get_record_with_names', for 'dbase_replace_record', 'dbase_add_record', or 'dbase_delete_record', to work

<?php

// open in read-write mode
$db = dbase_open('/tmp/test.dbf', 2) or die("Error! Could not open dbase database file /tmp/test.dbf.");        // 0=RO, 1=WO, 2=RW

// gets the old row
$row = dbase_get_record($db, 1);

// remove the 'deleted' entry from the array
unset($row['deleted']);

// Update the date field with the current timestamp
$row['date'] = date('Ymd');

// Replace the record
dbase_replace_record($db, $row, 1);
dbase_close($db);

?>

Actually you have to change the read array from key based to element (numeric) based and everything works correctly!

<?php
     $db = dbase_open( "yourfile.dbf", 2); // 0=RO, 1=WO, 2=RW
     if ($db) {
        $row = dbase_get_record_with_names($db, 1);
        unset($row["deleted"]); // drop the field
// do whatever it is you want to the $row["elements"]
// then convert to numeric to store:
        $rarr = array();
        foreach ($row as $i=>$vl) $rarr[] = $vl;
        dbase_replace_record($db, $rarr, 1);
        dbase_close($db);
    }
?>

That code actually works!

If you get "unexpected error", try to change the assoc array, $row, to an indexed array with array_values().

Example:
<?php
$row = array_values($row);
dbase_replace_record($db, $row, 1);
?>

The dbase_replace-function cannot handle an assoc array.

Hope this will save someone a headache! ;)

The dbase add and replace functions do NOT like to use the associative array.

<?php
//This gives "unspecified error" on replace and add:
$row = dbase_get_record_with_names($db, 1);
unset($row['deleted']);
dbase_replace_record($db, $row, 1);
dbase_add_record($db, $row);

//To further prove the point,
//The first add works, the second one fails:
$testrow1=array('one','2','three');
dbase_add_record($db,$testrow1);
$testrow2=array('FIELDA' => 'xxx','FIELDB' => '9','FIELDC' => 'yyyyy');
dbase_add_record($db,$testrow2);
?>
